Discover Planets Beyond Earth
Free · In‑App Purchases · Designed for iPad
6,000+ confirmed exoplanets from leading scientific archives. Compare alien worlds, explore habitable zones, and track the latest discoveries.
Explore the universe of exoplanets — over 6,000 confirmed worlds orbiting distant stars, updated from leading scientific archives. Track new discoveries as they happen and dive into the data behind every planet.
EXPLORE THE COSMOS
Search, filter, and sort the complete catalogue of confirmed exoplanets. Find planets by discovery method, star type, orbital characteristics, or habitability potential. Every entry includes detailed scientific data from peer-reviewed sources.
COMPARE WORLDS
Analyze exoplanets side-by-side — or compare them with Solar System planets like Earth, Jupiter, and Mars. Compare sizes, masses, orbital periods, star properties, and habitability scores to understand what makes each world unique.
HABITABLE ZONE VISUALIZATION
See exactly where planets orbit within their star's habitable zone — the region where liquid water could exist. Identify potentially Earth-like worlds and understand the conditions for life beyond our solar system.
